发明名称 Power supply apparatus and image forming apparatus including the same
摘要 A power supply apparatus switches between normal operation mode and power saving mode, to supply power to the loads. Power supply apparatus includes first power supply, second power supply, current detection portion, determination portion, and supply control portion. First power supply is configured to supply power to plurality of loads. Second power supply has an output current capacity which is less than that of first power supply. Current detection portion is configured to detect current consumption of first load that is operating. Determination portion is configured to determine whether or not the current consumption detected by current detection portion is less than or equal to the output current capacity of second power supply. Supply control portion is configured to supply, based on a result of determination made by determination portion, power to the first load from one of first power supply and second power supply in the power saving mode.

主权项 1. A power supply apparatus that switches between a normal operation mode in which power is supplied to a plurality of loads including a first load and a power saving mode in which power is supplied to a part of the loads including at least the first load, to supply power to the loads, the power supply apparatus comprising: a first power supply configured to supply power to the plurality of loads; a second power supply having an output current capacity which is less than that of the first power supply; a current detection portion configured to detect current consumption of the first load that is operating; a determination portion configured to determine whether or not the current consumption detected by the current detection portion is less than or equal to the output current capacity of the second power supply; and a supply control portion configured to supply, based on a result of determination made by the determination portion, power to the first load from one of the first power supply and the second power supply in the power saving mode.
